E&H D9FB Ultrasonic concentration meter

E&H D9FB Ultrasonic concentration meter

Overview of the E&H D9FB Series

The D9FB series is built around a full-bore, pressure-loss-free design with nominal diameters spanning DN 8 to DN 25 (3/8″ to 1″)-16. Unlike traditional sampling-based methods that introduce delays and product waste, the Teqwave F enables continuous in situ measurement, eliminating the need for laboratory analysis and reducing operational expenditures.

Engineered with stainless steel wetted materials (1.4571 / 316 Ti) and robust surface acoustic wave technology, the D9FB series reliably detects even the smallest concentration changes in process liquids, offering maintenance-free operation across a wide range of industrial environments-16-3.

Three Series Models: D9FB08 / D9FB15 / D9FB25

The D9FB family is organized into three distinct model groups, each optimized for specific pipe diameter requirements:

E&H D9FB08 – Compact Inline Concentration Meter

The D9FB08 is designed for smaller process lines requiring precise concentration monitoring in tight spaces. Suitable for applications where space constraints and high accuracy are paramount, this model excels in skid-mounted systems and compact industrial equipment. It operates with full-bore design ensuring zero pressure drop.

E&H D9FB15 – Mid-Range Process Meter

The D9FB15 serves standard industrial pipe diameters with balanced performance across concentration, density, sound velocity, and temperature measurements. Ideal for continuous quality control in mid-scale chemical blending, food processing, and pharmaceutical manufacturing lines.

E&H D9FB25 – High-Capacity Concentration Meter

The D9FB25 handles larger pipe diameters up to DN 25 (1″), delivering the same high precision across wider flow rates. Particularly suited for pulp and paper processing, mining slurry concentration monitoring, and high-volume industrial liquid analysis-10.

All three models share identical measurement accuracy and communication capabilities, differing primarily in nominal diameter range and maximum flow capacity.

This modular ordering system enables precise configuration of the Teqwave F meter to match specific process requirements. Users can customize wetted materials, communication protocols (4–20 mA or Modbus TCP), display options, and application packages based on the target liquid and measurement needs-1.

Technology: Surface Acoustic Wave (SAW) Measurement

The D9FB series employs surface acoustic wave technology, where acoustic waves propagate along a waveguide in direct contact with the process liquid. The device simultaneously measures sound velocity, density, and temperature – three independent parameters that enable precise concentration determination through predefined application algorithms.

Key technological advantages include:

Multivariable measurement: Single device outputs concentration, density, sound velocity, and temperature, reducing the number of required measurement points-3.

Real-time response: Continuous inline monitoring eliminates sampling delays and product waste common with laboratory analysis-35.

Zero maintenance: No moving parts and robust stainless steel construction ensure long-term reliability without regular servicing-3.

Full-bore design: No pressure loss means no additional pumping energy is required – a critical advantage for energy-sensitive processes-16.
